Revert of Flip mac full builders to GN.

Revert of Flip mac full builders to GN. (patchset #1 id:1 of https://codereview.chromium.org/2094783003/ )

Reason for revert:
Breaking Mac builders on chromium.perf and tryserver.chromium.perf.

Original issue's description:
> Flip mac full builders to GN.
> 
> This flips the 'Mac' build on the 'chromium' waterfall and the
> 'Google Chrome Mac' build on the 'chromium.chrome' waterfall to GN.
> If this sticks overnight, we can try to flip the official builders
> to GN in the morning. This also flips the 'mac_chromium_archive_rel_ng'
> MB config to match the 'Mac' config so that we can test builds more
> effectively.
> 
> The official build still isn't "right", since we haven't ported over
> the installer for the remoting me2me host. I'm going to try and work
> around that for now so that we can see what else might be missing.
